"Psychological projection is the process of misinterpreting what is "inside" as coming from "outside". - - In its malignant forms, it is a defense mechanism in which the ego defends itself against disowned and highly negative parts of the self by denying their existence in themselves and attributing them to others, breeding misunderstanding and causing untold interpersonal damage."
Soviet Movies, left to right:
Guest from the Future (Гостья из Будущего), Per Aspera ad Astra (Сквозь Тернии к Звездам)
Moscow-Cassiopeia (Москва-Кассиопея), Guest From the Future (again)
Kin-Dza-Dza (Кин-дза-дза), The Witches Cave (Подземелье Ведьм)
Moscow-Cassiopeia (again), This Merry Planet (Эта весёлая планета)
I don't know this one, She Fell from clouds (Spadla z oblakov)
I mean, I get what you're saying, but the real takeaway here seems to be that US filmmakers had access to better creature effects than Soviet filmmakers.
I don't think that's necessarily true, the soviets weren't that far behind on special effects technology. Especially in the practical realm. There was just a divide between what kind of media was consumed in America and the USSR.
Most of the extra terrestrial body horror stuff of that era was absolutely meant to be a critique of America though.
